Description

Apparatus to maintain horizontality of floating matters on the sea}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for leveling a seafloat, and more particularly, it is installed in a seafloat that may cause unstable agitation, for example, rolling, such as a ship, thereby reducing the rollover. The present invention relates to an apparatus for leveling a marine float such that a marine float such as a ship can be kept as horizontal as possible.

In recent years, as the performance of civilian ships and military ships has been improved, the necessity of reducing the movement of the ships and controlling the attitude is increasing. For example, a passenger on board a passenger ship may experience extreme fatigue and discomfort when the passenger ship is continuously flowing due to a blue wave (when it is swayed in the transverse or longitudinal direction). This may cause a failure in safety operation by committing an error of judgment or the like.

In addition, if the vessel is not maintained in a stable manner, there is a fear that a failure of the onboard equipment occurs, and in the case of a high-performance sea vessel may not be able to operate at all because the attitude control is not properly performed.

In particular, in order to improve the efficiency of transportation in recent years, the transport work is not carried to the port but the transport work is carried out by a crane installed in the middle of the sea. If not, the transportation work may not be performed properly, and an accident may occur during the transportation work.

Therefore, the reduction of motion and attitude control of the vessel is very important. Thus, the vessel can be equipped with posture control equipment for performing posture control by reducing the ship's motion.

On the other hand, ships in the blue generally have six degrees of freedom, of which movement, particularly in the transverse direction (left and right directions), ie rolling, affects the passengers a lot. Therefore, the attitude control equipment to reduce the lateral fluctuation by using the movable mass has been developed and used in practice.

1 is a view showing a schematic shape and a movement of a horizontal holding device for reducing lateral fluctuations according to an embodiment of the prior art.

As shown in the drawing, the posture control device according to an exemplary embodiment, that is, the horizontal holding device 1 is mounted on the deck 5 of the ship 3 and the like and has a rail having a curved rail 11 having a predetermined radius of curvature. The body 10 and the movable mass 40 which move along the curved rail 11 of the rail body 10 are provided.

Here, the rail body 10 is mounted in the horizontal direction of the ship 3, ie, the left-right direction, and the movable mass 40 is provided in the spherical shape which has a predetermined weight.

By this structure, for example, when the ship 3 tilts to the left based on FIG. 1, the movable mass 40 moves to the right on the curved rail 11. Therefore, the degree of energy can be canceled, thereby reducing the lateral fluctuations.

By the way, in the horizontal holding apparatus 1 according to the conventional embodiment, the movable mass 40 is moved when the ship 3 is tilted, but the lateral fluctuation of the ship 3 can be reduced to some extent. In the case where the degree of blue wave is excessively swayed in the caster 3, the degree of agitation of the ship 3 cannot be accurately compensated only by the operation of the movable mass 40, so that the sway can not be reliably reduced. There is this.

On the other hand, in addition to the leveling device 1 having such a configuration, a leveling device having another configuration, for example, a leveling device for reducing the lateral fluctuation of the ship by using the movement of the movable mass in the form of a liquid, has been considered. The holding device also has a disadvantage in that it is difficult to precisely control the moving mass, so that the lateral fluctuation of the ship cannot be reliably progressed.

Can be. However, the present invention is not limited thereto, and the moving body 141 may be integrally formed.

Positioning roller 150, while the moving body 141 moves along the guide portion 110, while the movement is made smoothly, and also maintains the position of the moving body 141 relative to the guide portion 110 Play a role.

As shown in FIG. 4, the position adjusting roller 150 includes a pair of first rollers 151 disposed on the bottom surface of the upper plate 142 of the moving body 141 and the moving body 141. And a pair of second rollers 155 disposed on the inner surface of the front and rear side plates 143.

The pair of first rollers are disposed at both side regions of the bottom surface of the upper plate 142 of the movable body 141 to be in contact with the upper surface of the guide unit 110, and thus the movable body 141 along the guide member 115. ) Is to prevent the position change in the height direction when moving.

In addition, the pair of second rollers 155 are respectively coupled to the inner side of the front and rear side plates 143 of the moving body 141 to be in contact with the extension body 117 of the guide member 115 and thereby guide the guide member 115. Accordingly, it serves to prevent the position change in the front and rear direction when the moving body 141 moves.

By the first roller 151 and the second roller 155, the moving body 141 can move smoothly in the left and right directions along the guide member 115 of the guide portion 110, but at this time, the front and rear direction or height By maintaining the position in the direction, it is possible to eliminate that the position control of the lateral fluctuation reduction unit 140 relative to the guide portion 110 is affected by the position change in the other direction.

In addition, the first roller 151 and the second roller 155 are provided with a rubber material capable of shock absorption. Therefore, even if a strong impact is applied to the vessel 103 from the outside and the lateral fluctuation reducing unit 140 vibrates with respect to the guide unit 110, the first roller 151 and the second roller 155 may absorb the impact. It is possible to prevent the occurrence of breakage due to impact or the like.

On the other hand, as shown in Figure 4, the length body 116 of the guide member 115 is provided with a recessed groove 116a recessed inwardly from the top surface in the longitudinal direction of the length body 116, and moved A protruding member 142a partially inserted into the recessed groove 116a is protruded from the bottom of the upper plate 142 of the body 141.

Since the protruding member 142a and the recessed groove 116a are provided in a shape corresponding to each other, the protruding member 142a and the recessed groove 116a may not only reinforce the fixing force of the lateral fluctuation reducing unit 140 with respect to the guide unit 110 but may also improve the guide effect. .

On the other hand, the lateral shake reduction unit 140 is moved along the longitudinal direction of the guide unit 110, but must be moved to one position of the guide unit 110 to offset the degree of lateral shake occurs.

To this end, the horizontal holding apparatus 100 of the marine floating material of the present embodiment, as described above, the drive unit 170 for generating a driving force for driving the lateral fluctuation reducing unit 140, and the lateral fluctuation of the vessel 103 Degree, that is, the inclination angle detection sensor for detecting the energy level of the vessel 103, and the control unit for controlling the movement of the lateral shake reduction unit 140 by the drive unit 170 based on the detection information of the inclination angle detection sensor. .

First, the configuration of the drive unit 170, the drive unit 170 of the present embodiment, as shown in Figs. 4 and 5, each of the guide portion 110 and the sideways reduction unit 140 It is provided in part to generate a floating force of the lateral shake reduction portion 140 with respect to the guide portion 110 by magnetic interaction, and the guide portion 110 and the lateral shake reduction portion 140 respectively. It includes a linear driving unit for linearly moving the lateral fluctuation reducing unit 140 with respect to the guide unit 110 when alternating current is applied.

By the configuration of the drive unit 170, first, the lateral fluctuation reducing unit 140 may be floated with respect to the guide unit 110, and also the linear movement of the lateral fluctuation reducing unit 140 with respect to the guide unit 110. This can be done.

Referring to each configuration, first, the floating drive unit, as shown in Figure 5, the magnetic magnet (181, magnet) coupled to the extension body 117 of the guide unit 110, and the magnet 181 A core 185 mounted on the upper surface of the lower plate 144 of the movable body 141 and a coil 187 wound around the core 185 to be applied magnetically are applied thereto.

When a current is applied to the coil 187 by this configuration, the magnetism is generated in the core 185, and the magnetism generated in the core 185 and the magnetism of the magnet 181 are the same, so that the core 185 and the magnet ( 181 are spaced apart from each other by repulsive force. That is, when the current is not applied, the magnet 181 and the core 185 remain in contact with each other, but when a current is applied, repulsive force is generated between the magnet 181 and the core 185 so that the core 185 is the magnet 181. In this case, the linear movement of the lateral fluctuation reducing unit 140 which is held in a restrained state with respect to the guide unit 110 is possible.

On the other hand, after separating the magnet 181 and the core 185 by the floating drive in this way, the lateral fluctuation reduction unit 140 moves in a direction to reduce lateral fluctuations, such a lateral fluctuation reduction unit 140 The linear movement of is performed by the linear driver 190.

As shown in FIG. 5, the linear driving unit of the present exemplary embodiment may be configured of the above-described magnet 181 and the core 185 on which the above-described coil 187 is wound. That is, the magnet 181 generating the floating force and the core 185 on which the coil 187 is wound may be used as the linear driving unit as well as the floating driving unit.

As described above, the magnet 181 is provided long along the longitudinal direction of the length body, that is, along the moving direction of the transverse shaking lower portion 140, and as shown in Figs. 4 and 5, the coil 187 is The wound cores 185 are provided in pairs along the longitudinal direction in both regions of the guide part 110.

Here, when the current is alternately applied to the coils 187 wound on the pair of cores 185, that is, when alternating current is applied, the cores 185 on which the coils 187 are wound with respect to the magnet 181 are linear. I can move it. In other words, the transverse fluctuation reduction part 140 in which the core 185 is mounted may linearly move with respect to the guide part 110 to which the magnet 181 is coupled.

As described above, the drive unit 170 including the floating drive unit and the linear drive unit lifts (spaces) the core 185 mounted on the horizontal shaking reduction unit 140 with respect to the magnet 181 mounted on the guide unit 110. Afterwards, by applying alternating current to the coils 187 wound around the cores 185 provided in pairs so as to be symmetrical to each other, the lateral fluctuation reduction unit 140 may be linearly moved relative to the guide unit 110. Accordingly, the lateral shake reduction unit 140 can be moved to a position where lateral shaking is reduced.

On the other hand, in order to reduce the lateral oscillation of the vessel 103 by the above-described drive unit 170, after detecting the lateral oscillation degree of the vessel 103, the lateral oscillation for the guide unit 110, based on the detected information The movement of the reduction unit 140 must be really controlled.

To this end, as described above, the horizontal holding apparatus 100 of the sea floating material, the tilt angle detection sensor (not shown) for detecting the degree of lateral shaking, that is, the energy of the ship 103, and the tilt angle detection sensor It includes a control unit (not shown) for controlling the position of the lateral shake reduction unit 140 relative to the guide unit 110 by the detection information.

The inclination angle sensor detects the level of energy in the horizontal plane when the horizontal shaking occurs, compared to the horizontal surface when there is no horizontal shaking. The inclination angle sensor may be mounted on a horizontal surface such as a horizontal plate 111 of the guide unit 110, and transmits the detected information to the controller.

The controller determines the magnitude of the current and the direction of the current applied to the driving unit 170 based on the sensing information from the tilt angle detecting sensor. Accordingly, the driving unit 170 may not only apply a predetermined amount of current to the coil 187 wound on the core 185 according to a command of the controller, but also alternately apply currents in a predetermined order (different current directions). It is possible to apply, so that the horizontal shake reduction unit 140 can be linearly moved to a desired position.

Meanwhile, as shown in FIG. 3, the horizontal holding apparatus 100 of the marine floating material of the present embodiment is transverse to the center portion of the guide part 110 when no current is applied, that is, when the driving unit 170 is not driven. The shake reduction unit 140 may further include a fixing bracket 160 to fix the lateral shake reduction unit 140.

As described above, when the current is not applied, an attraction force may be generated between the core 185 and the magnet 181 so that the position of the lateral fluctuation reducing unit 140 with respect to the guide unit 110 may be maintained. In this case, the lateral shake reduction unit 140 may be out of the fixed position of the guide unit 110. However, in the present embodiment, even when a strong shock is applied from the outside when no current is applied, the lateral sway reducing unit 140 is arbitrarily fixed by the fixing bracket 140 coupled to the guide unit 110 to secure the lateral sway reducing unit 140. You can stop moving.

Here, the fixing bracket 160 may be variously fixed in the method of fixing the lateral shake reduction unit 140, but a coupling groove in which a portion of the fixing bracket 160 is detachably coupled to the lateral shaking reduction unit 140 is detachable. (Not shown) and by selectively coupling the fixing bracket 160 to such a coupling groove, it is possible to fix the lateral shake reduction unit 140 by the fixing bracket 160 when no current is applied.

Hereinafter, a driving method of the horizontal holding device 100 having the above-described floating object will be described with reference to FIG. 6.

For example, as shown in FIG. 6, when the ship 103 is swayed to one side, the inclination angle α with respect to the horizontal plane is sensed by the inclination angle sensor and transmitted to the controller. Then, the control unit drives the driving unit 170 based on the received information to control the position of the lateral shake reduction unit 140 with respect to the guide unit 110. That is, based on Figure 6, since the ship 103 is inclined to one side, the lateral shake reduction unit 140 having a predetermined weight must be moved in the other direction opposite to one side, to generate the necessary driving force at this time The control unit controls the operation of the driving unit 170.

As described above, according to the present embodiment, even if the sea floating material such as the ship 103 is laterally shaken due to external factors, by using the horizontal holding device 100 of the sea floating material mounted on the ship 103, that is, By precisely controlling the position of the lateral reduction unit 140 with respect to the guide unit 110, there is an effect that can significantly reduce the lateral fluctuation.
